100A residential service went underground in early 1970s (California); AFAIK untouched since then. Service rises above ground outside corner of attached unfinished garage, enters through wall, then bends up 90 degrees to run up inside of wall and bends to enter in-wall-mounted meter from above.
Recently removed 25-year-old cardboard box that had blocked view of part of initial in-garage section of service entrance area conduit (still upstream of meter) and noticed the conduit has a gap in it !?! with apparently 3 service cables visible. Since the conduit seems to be secured nearby in both directions, maybe someone left it unfinished and forgot to come back and complete it?? To me, it seems the right end is 3-4 inches out of position, so I don't think it was just someone bumping previously mated conduit.
Can I fix it and should I fix it? If so, what's a good way (I have class 00 rubber gloves, insulated electrician's screwdrivers and pliers)? It doesn't look to me like I can just pull the two conduit pieces together and tighten the two screws. Is this section of conduit my responsibility or the utility's? (inside garage, but still upstream of meter) I would really like to avoid calling the utility for at least the next few weeks, as we have activities scheduled and limited time for appts etc.
Gap area of conduit:
Outside view of conduit entry - note 3/4" gap in caulking, as if conduit has pulled back relative to house.
Cleaned-off gap region showing only 1 screw divot perhaps 1/4" from end of right conduit.
Inside section of conduit from gap running up wall (by stud, but not secured anywhere other than plumber's wrap at bottom and connection to meter on top), then sideways and connection to meter:
Update - my theory based on harper's, ed's, dan's and the other very helpful comments: (more photos added)
Original installation had gap closed, but with only a tiny overlap barely enough for one set screw to be tightened (single screw divot visible right at end of right conduit on new photo with conduit brushed off; former black oval was just debris). Plumbers strapping may have been original; from ground outside up until connection to meter, conduit is secured nowhere else.
At some point, conduit outside at wall entry moved out about 3/4" relative to wall, as shown by gap in caulking. I think this is sufficient to explain the gap in the conduit -- with only one screw securing the inside connection and the strapping preventing the sweep/vertical run from following along, the connection separated.
Update - My Plan:
As suggested in answers, remove plumbers strapping
As suggested in answers, undo the 2 set screws on connection by gap; gently manhandle right sweep into connector past both screws and tighten set screws appropriately (anyone have a suggested torque?). Perhaps I should secure vertical stretch of conduit first so as to not stress conduit attachment to meter.
Secure incoming conduit before connection and after connection to wall studs or blocking using proper straps. Also secure vertical segment to stud/blocking using proper strap. 3 new straps in total - one before gap, one after, one on vertical. Is that sufficient?
Finally, a big thanks for the great answers and comments! I have not dealt with metallic conduit before and it was nice to learn this seems like a straightforward fix.
Found this related question which is for outdoor PVC conduit but suggests the conduit section is my responsibility, not the utility's: Gap in conduit running to electric meter
